Henge Docks, well known for its MacBook Pro docking stations, has announced a new model at the Consumer Electronics Show (CES) in Las Vegas: the Horizontal Dock, a $249 combination riser and docking station specifically for the MacBook Air and Retina MacBook Pro. The new dock stands in stark contrast to the company's vertically-oriented AirDock and Henge Docks that allow users to run and hook monitors to MacBooks with the lid closed.
